Figure 6: Growth dynamics of rat aortic smooth muscle cells in cultures on nonmodified PE (pristine), on PE irradiated with plasma (plasma), on PE irradiated with plasma and grafted with glycine (Gly), on polyethyleneglycol (PEG), on bovine serum albumin (BSA), on colloidal carbon particles (C), or on bovine serum albumin and C (BSA+C). A tissue culture polystyrene dish (PS dish) was used as the reference material. Means from three samples for each experimental group and time interval (each sample measured 50 times).
